const [completedTodos, setCompletedTodos] = useState<Todo[]>([])

Underutilizing reducers

Not writing unit tests for the low-hanging fruit

Underutilizing React.memo, useMemo, and useCallback

Writing useEffects that run too often or not often enough

Not considering usability

Not working towards mastery of CSS & web design

General Best Practices

Colocate styles with components
